I agree that some see it as Dr. Freud did, but I personally have a theory that it runs deeper than that. Being one who has worked with people exhibiting these behaviors, I believe one may associate food with sexual activity for a number of reasons. Bear in mind that this is only theory on my part, and i have not had the ability, before now to test it. I think, we will learn, that in some cases, food is an attempt to cover for aggression, or to provide a way out for loneliness, as has been proven. However, I also believe food may act as an actual substitute partner for some. I have had patients in the past refer to food as "their lovers" and "making love to food" in a philosophical sense. I have also known someone personally, who struggles with a food addiction, and she can actually achieve climax while eating a certain type of food. I do not wish to divulge too much, in keeping her confidentiality, yet she has assured me I may speak on her case, and she is actually able to achieve a level of arousal, and orgasm, when eating danish. She also is able to achieve the same when eating a large amount of chocolate.
